how to get the list of devices which are registere

问题:

after reading the sample code for my server:

// Replace with real BROWSER API key from Google APIs
$apiKey = "123456";

// Replace with real client registration IDs 
$registrationIDs = array( "123", "456" );

// Message to be sent
$message = "x";

// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';

$fields = array(
             'registration_ids'  => $registrationIDs,
             'data'              => array( "message" => $message ),
              );

$headers = array( 
                 'Authorization: key=' . $apiKey,
                 'Content-Type: application/json'
             );

// Open connection
$ch = curl_init();

// Set the url, number of POST vars, POST data
curl_setopt( $ch, CURLOPT_URL, $url );

curl_setopt( $ch, CURLOPT_POST, true ); 
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );

// Execute post
$result = curl_exec($ch);

// Close connection
curl_close($ch);

it is required to know the registration_ids from the server to push information.

You don't. As you noted, you have to send the registration ID from the device to your server, by one means or another (e.g., Web service).

There is no built-in means of doing this, short of you sending a message to all of your registered devices by their registration IDs.
